This projects makes my dream come true - write my own operating system. I'm doing this mostly for fun, so don't expect a fully-fledged operating system on basis of the RISC-V architecture.
Exactly like SerenityOS this project doesn't use third-party runtime dependencies. If third-party dependencies are used, then only for the Build.
I started doing some coding videos on Youtube. Go and check it out if you want sysheap channel
Implemented
- Page allocator
- Heap allocator
- Interrupt handling (PLIC -> UART interrupts)
- Testing harness
- Executing in supervisor mode
- Userspace processes
- Scheduler
- Systemcalls
- Networkstack (udp)
- SMP
TODO
- VirtIO / Filesystem
- TCP
- Async Runtime in Kernel
- GUI
- See todo
To run the operating system you need to have the following tools installed:
- Rust
- just
- nextest
- qemu-system-riscv64
- binutils-riscv64-linux-gnu
To install them on Ubuntu you can execute the following commands
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
sudo apt install qemu-system-riscv64 binutils-riscv64-linux-gnu
cargo install just cargo-nextest --locked
To run the operating system execute
just run
Type help into the shell to get some information. If you type the name of a program it get's executed. If you add an ampersand at the end of the command it get's executed in the background. See src/userspace/src/bin for programs which can be executed.
The justfile contains useful commands which I often use. To run them you first need to install just (just a command runner).
cargo install just. To get a list of all commands execute just -l.
